AivSp-ecillaation of Letters Patent. Patented Dec. 10, 1912.

Application tiled January 20, 1912. Serial lo. 672,369.

Be it known that I, THOMAS T. CHAIQNER, a citizen of the United States,and a resldent of the cit-y of New York, borou h of Manhattan, in thecounty and State o New York,

have invented a new and vImproved Vehicle- Wheel, of which the followlng1s a full, clear, and exact description.

The invention relates more particularly a resilient wheel and has as anob]ect the: provision of improved means for resillently supporting anouter rim or tread membergf Another object of the invention 1s theprevision of an improved wheel structure formed with an outer rim suported by' springs and a plurality of projecting beyond the rim.

ln carrying out the ob'ects ,of the 1nv en tion, a hub and spokes o anydes1red `kind may be used, together with 'a felly and rlm of anypreferred structure. Mounted on the rim is a tire or movable rim theelly by a plurality springs are supported and hel in place by suitableplugs threaded into the felly and extending into the lixed'rim on thefellyso that when in operation the removable rlm will resiliently moveas occasion ma require, the same being guided by suitable guidewayswhich prevent independent rotation of the removable rim but permit afree radial motion thereof. Associated with the movable rim is aplurality of plugs extending therethrough and through a rubber t-1remounted thereon. These plugs are formed preferably of rubber so as toactas antiskidding devices as well as resilient suports. p A practicalembodiment of the invention is represented in the accompanying drawingsforming a part of this specification, 1 1; which similar characters ofreference indiresllien-t plugs cate corresponding parts in all theviews.

Figure, 1 1s a fragmentary side "view of a wheel showing an embodimentof the invenbetter 1 section through Fig. 3; and Fig.

certain parts being broken away t0 illustrate the construction Fig. 2 isa Fig. 3 on the line 2 2 of 3 is a sectionv through Fig.

2 approximately on the line Referrin to the accompanying drawings bynumera s, 1 indicates spokes of any desired kind, to lwhich is secured af elly 2 and a xed rim 3. The fixed rim 3 and the fellv 2 are made ofmetal or an other material.' Mounted on the rim 3 and elly 2, are aplu-` lt-ire 10, the plug 9 VOn the sections 4 there held away from, ofls rings. -The v rality of channel-shaped members 4 having channel-shapedprojections 5 formed thereon for fitting are held against anyconsiderable independent longitudinal movement by plugs 6, which alsohold a spring 7 properly in place againsta retainlng cap-shaped washer8. The washer 8 is designed to hold the plug 9 correctly in a and tire10 being preferably formed of rubber' of some good quality. are arrangedone or more channels 11 which accommodate antifriction members 12, andalso projections or pins 13 extending from an annular movable rim 14formed preferably substantially channel-shaped in cro-ss section, asshown in Fig. 3. These channels are preferably arranged parallel withthe centerline 'of the respective spokes 1, with sufficient play forallowing a proper radial movement of the rini 14 without causing anybinding. It will be evident that as the radial movement of the rimmovement will be unappreciable.

In use, the plugs 9 will act as a protection for the'tire 10, and alsoas anti-skidding devices. In case a heavy pressure should bear againstany of the plugs 9, the same will simply move inward and compress thespring 7 to a greater extent and will then move outward again when thepressure has been removed. In case any of the springs 7 should break, orit is desired to remove any of thev plugs 9, the screw plug 6' may beremoved, which will permit ready access to the spring 7, washer 8, andalso willl ermit the removal noted that each of the springs 7 isprovided with a plug 9 and .also the screw plug 6, so that any of the srings or plugs may be repaired or renewe without taking the entire wheelto pieces the remaining parts of the wheel.

The anti-friction balls 12 are designed to make the movable rim`14 moveeasier, and

to do away with squeaking and other noises to a large ext-ent. However,lto positively prevent any squeaking, the tire 10 is formed` withdepending port1ons 15 and 16 which 14 is comparatively small, each oraffecting any of over the stationary rim 3 and Vfelly 2. The sections 4of the plug 9. It wil be extend downward between the flanges of the rim14 `and the flanges .of the sections 4, as more clearly shown in Fig. 2,whereby the telescoping members may rub against a yielding surfaceuntil' the. same has been worn to a considerable extent.

Having vthus described my invention I claim as new and desire to secureby Letters Patent 1. The combination with a vehicle wheel, of aplurality of independent sections formed with ways therein, a movablerim formed with pins 'projecting into said ways, anti-friction memberssupported by said pins and arranged-to prevent the pins from engagingthe sides of -said sections, and a plurality of springs for resilientlysupporting said movable. rim.

2. The combination with a vehicle wheel, of a movable rim, a pluralityof springs engaging the under surface of said rim for yieldingly holdingthe same in`a predetermined position, an adjust-ablev supporting memberfor each of said springs, a tire mounted on said rim, and a plug on'each of said springs extending through said tire and said rim andengaging said springs for being independently supported thereby.

- 3. The combination withla vehicle wheel, of a movable rim, a'plurality of loosely arranged lates engaging the under surface of therim, a plurality of springs engaging the under surface of said platesfor yield- ,ingly pressingthe same againstsaid rim and name to thisspecication in the yieldingly holding the rim in apredeterminedposition, a tire mounted on said rim, and a plugifor each of said platesextending through said tire and said rim, and resting on said plates forbeing independently supported by said plates and said springs.

4. The combination with avehicle wheel, of a plurality of substantiallychannelshaped sections formed with guiding ways, a movable rim formedwith projections ex tending into said ways whereby the movable rim isguided in its movement, a plurality of springs engaging the undersurface of said rim for yieldingly holding the same `in a predeterminedfposition, an adjustable or each of said sprinffs,.V

supporting member a tire mounted on said rim, and a plug or each of saidsprings extending through said tire and said rim and engaging saidsprings for being supported thereby.

In testimony whereof I have signed my presence of 'two subscribingwitnesses.
